METHOD OF SAND-BLAST RELIEF CARVING.

Application filed September 1, 1926, Serial No. 133,074. Renewed February 24, 1927.

This invention relates to an improved molasses. After the coating has been apmethod of producing relief carving on stone plied and allowed to set and harden somethrough sand blasting and has for an object what, a desired flower or other confi ration to provide a minimum number of steps for 2 is applied tothe coatin This ower or producing a desired shape in relief. other configuration may be transferred to on Another object of the invention is to prothe coating through the action of a decalvide a method wherein flowers or other concomania or in any-other way, as for instance, figurations may be carved by sand blast to by the flower being drawn directl on the roduce a substantially life-like appearance coating. In Figure 2, the flower has been in relief. shown as having thickness but this is not 05 In the accompanying drawings-- essential and it is only shown in this manner Figure 1 is a plan and section showing a for illustrating how the flower is applied. stone with a coating applied thereto. After the flower has been applied, a sin le Figure 2 is a view similar to Figure 1 but slit or cut is made around the border of t e us showing an ornamentation applied thereto. flower, leaves and other configurations as 70 Figure 3 is a view similar to Figure 2 exindicated in Figure 3 and then the coating 1 cept that it shows the coating cut. removed where the flowers are to be formed.

Figure 4 is a view similar to Figure 3 After the material has been removed as just with certain parts removed exposing that described, the stone will appear as shown in 2 part of the stone which is to be formed into Figure 4. A sand blast is then applied to 75' a flower or other configuration. the exposed part of the stone so that a sink Fi re 5 is a view similar to Figure 4 but age 3 is provided for the various parts of showing the sinkage formed by sand blastthe flower. In order to provide a sharp edge ing, the same showing the central portion of to the blossom, leaves and other parts of e 2 the flower, leaves, etc. flower, a fillin 4 is provided in the sinkage 80 Figure 6 is a view similar to Figure 5 but 3, said filling ing preferably of the same showing the sinkage filled with a yielding material as coating 1. After the filling has substance adapted to resist the action of the been applied as shown in Figure 6, a small sand blast. and narrow outline is cut around the various Figure 7 is a view similar to Figure 6 but parts of the flower and other configuration 85 showing the parts cut around the sinkage and this outline is removed as shown in the and around the border with the out parts sectional portion of Figure 7. The sand removed. blast is then used to provide a strai ht sink- Figure 8 is a sectional view similar to the age as shown in Figure 8 so that t e outer section shown in Figure 7 except that it edge of the blossom and other parts of the go shows sand blast grooves out where the coatflower will have a straight outer wall while ing has been removed. the sinkage 3 is curved and otherwise Figure 9 is a view similar to Fi ure 8 exformed to indicate the shape of the face of cept that it shows a coating aroun the flowthe flower.

This will cause the flowers which Figure 11 is a sectional view through Fighave been formed to set up in relief. After 10 ure 1 on line 11-11. the background has been sand blasted to the In carrying out the method of producing desired depth, the remaining part of the a finished sand blast carving as illustrated coating 1 is removed, said removal bein by in Figures 10 and 11, a stone of the desired a knife or in any other desired way. hen

size is secured and finished on one face. The this has been done the finished product will 1 finished face is then provided with a coating be seen as shown in Figures 10 and 11 with 1 of material which will resist appreciably the flowers and other configurations propthe action of a sand blast. This coating may erly formed and disclosed in relief. It will be any rubber like composition, as for inthus be seen that the method includes the as stance, a mixture of glue, water and cane provision of a stone having a smooth side no which is painted or covered with coatin 1 and then the flowers are transferred to t is surface, after which the outlines of the flowers are cut by a sharp tool and the part above where the flowers are to be formed is removed. After the sinkage has been produced for the flowers or other configurations, the same is filled with a coating similar to coating 1 and a very narrow outline is cut around the outline of the design exposin the stone so that a vertical or a straight sinkage may be produced as shown in Figure 8, after which the background or other undesirable parts are sand blasted away. In the drawings a border has been shown with certain ornamental configurations associated therewith in addition to the flower but it will be evident that a flower could be provided alone or a border could be provided alone as well as in association as shown.

What I claim is:

1. The method of forming sand blast carving presenting a relief efl'ect consisting in applying a coating to the surface of the stone, applying flowers or other configurations to the stone, cutting the outline of the flowers and removing the coating within the outline, sand blasting a sinkage in the exposed stone, cutting out and removing a narrow portion around the outer edge of the flowers, sand blasting the sinkage in said narrow outline, removing the remaining coating and sand blasting the background.

2. The method of sand blast carving including coating a stone, removing the coating at the points where a sinkage is desired, sand blasting the stone at the place the coating has been removed, said sand blasting being continued until the sinkage has been formed of the proper depth and sha e, re moving a narrow stri of coating a jacent the outer edge of sai sinkage, sand blasting the stone exposed by removing said narrow strip, removing the remaining coating, and then sand blasting the background between said sinka e.

3. The metho of sand blast carving including the coatin of a piece of stone to be carved, removing t ie coating where the sinkage is to be produced, sand blasting the stone at the parts where the coating has been removed and then removing and sand blasting the stone around the sinkage, said sand blasting bein done in two stages, the first being to sand %last a de ression around the sinkage and then san blast the parts between said depression.

4. The method of sand blast carving includin sand blasting a sinkage to secure a desire configuration, sand blasting a vertical wall around the outer edge of the sinkage and finally sand blasting all of the background around the sinkage.

5. A sand blast carving having a background, and a design formed thereupon in relief and having the face thereof formed with a sinkage, the side walls of said desi being substantially perpendicular to t 6 background to produce sharp edge around the design, said side walls extending to the base of a depression cut into the back round and following the contour of said re ief-design.

6. A sand blast carving formed integral throughout having a pitted background, and a design formed thereon in relief and having the face thereof formed with a sinkage of a contour to disclose the design, said face being pitted, the side walls of said desi being substantially perpendicular to t e background and said side walls extending to the background and substantially following the contour of said relief design.

7. A sand blast carving formed integral throughout having a pitted background, and a pitted design formed thereon in relief and having the face of the design formed with a sinkage of a contour to disclose the design, the side walls of said design being substantially perpendicular to the background, the perpendicular face of said side walls following the contour of said relief design.

8. A sand blast carving formed integral throughout having a pitted background, and a design formed thereon in relief, the side walls of said pitted desi n being substantially perpendicular to the background to produce a sharp edge around the design, said side walls extending to a position substantially in line with the background, and followin the contour of said relief design.

9. E sand blast carving having a pitted background, and a pitted design formed thereon in relief and having the face thereof formed with a sinkage of a contour disclosing the design, the side walls of said design being substantially perpendicular to the background and extending from the edge of the relief design to produce a sharp edge around the design, said side walls extending to a position approximately in line with the surface of the background and substantially following the contour of said relief design- GEORGE RANNIE PHILIP.
